Deuteronomy 25:7"But if the man does not desire to take his brother's wife, then his brother's wife shall go up to the gate to the elders and say, 'My husband's brother refuses to establish a name for his brother in Israel; he is not willing to perform the duty of a husband's brother to me.'

Deuteronomy 25:9then his brother's wife shall come to him in the sight of the elders, and pull his sandal off his foot and spit in his face; and she shall declare, 'Thus it is done to the man who does not build up his brother's house.'

Ruth 4:7Now this was the custom in former times in Israel concerning the redemption and the exchange of land to confirm any matter: a man removed his sandal and gave it to another; and this was the manner of attestation in Israel.

Then the elders of his city shall call him, and speak to him: and if he stand to it, and say, I like not to take her;

Then the elders of his city shall call him,.... Require him to come, before them, and declare his resolution, and the reasons for it; recite this law to him, and explain the nature of it, and exhort him to comply with it, or show reason why he does not, at least to have his final resolution upon it:

and speak unto him; talk with him upon this subject, and give him their best advice; and what that was Maimonides (o) more particularly informs us; if it is good and advisable to marry, they advise him to marry; but if it is better advice to pluck off the shoe, they give it; as when she is young and he is old, or she is old and he young, they advise him to allow the shoe to be plucked off:

and if he stand to it: and say, I like not to take her; if, after all the conversation, debate, and counsel between them, he is resolute, and abides by his first determination, that he will not marry her, then the following method was to be taken.
